Cov ntsiab lus
- Cov khoom xyaw tuaj yeem yog cais siv ntau yam txuj ci.
- Chromatography suav nrog kev sib cais hnyav ntawm cov khoom nruab nrab.
- Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub.
- Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv.
- Lim cais cov khib nyiab ntawm qhov sib txawv.
Ntawm no, 5 txoj hauv kev los cais qhov sib tov yog dab tsi?
Hauv qab no yog qee txoj hauv kev sib cais:
- Ntawv Chromatography. Txoj kev no feem ntau siv hauv kev lag luam khoom noj.
- Lim. Qhov no yog ib txoj kev ntau dua ntawm kev sib cais cov khoom insoluble los ntawm cov kua.
- Evaporation.
- Yooj yim distillation.
- Fractional distillation.
Tsis tas li, koj tuaj yeem cais ntau hom kev sib xyaw li cas? Ntau hom kev sib cais yog:
- Crystallization.
- Lim.
- Decantation.
- Sublimation.
- Evaporation.
- Yooj yim distillation.
- Fractional distillation.
- Chromatography.
Ua raws li qhov no, 7 txoj hauv kev los cais cov sib tov yog dab tsi?
Txheeb xyuas txoj hauv kev xaiv tes, Threshing, Winnowing, Sieving, Sib nqus Attraction, Sublimation, Evaporation , Crystallization, Sedimentation & Decantation, Chaw thau khoom, Lim , Distillation , Centrifugation, thiab ntawv Chromatography tuaj yeem siv tau hauv lub neej txhua hnub.
Dab tsi yog 10 txoj hauv kev ntawm kev sib cais sib xyaw?
Qee txoj hauv kev sib cais cov tshuaj los yog sib tov yog:
- Kev xaiv tes.
- Khaub ncaws.
- Winnowing.
- Sieving.
- Evaporation.
- Distillation.
- Lim los yog Sedimentation.
- Sib cais Funnel.

Koj yuav ua li cas cais ib qho khoom thiab sib tov?
Cov ntsiab lus sib xyaw tuaj yeem sib cais siv ntau hom kev kawm. Chromatography suav nrog kev sib cais hnyav ntawm cov khoom nruab nrab. Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub. Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv. Lim cais cov khib nyiab ntawm qhov sib txawv
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Koj tuaj yeem qhia tau li cas yog tias ob qhov sib npaug sib npaug?
Peb tuaj yeem txiav txim siab los ntawm lawv qhov sib npaug seb puas yog ob kab sib npaug los ntawm kev sib piv lawv cov nqes hav. Yog hais tias cov slopes yog tib yam thiab cov y-intercepts txawv, cov kab yog parallel. Yog tias txoj kab nqes sib txawv, cov kab tsis sib npaug. Tsis zoo li cov kab sib luag, cov kab perpendicular sib tshuam
Yuav ua li cas koj cais ib tug sib tov ntawm pigments los ntawm ib tug number case cartridge?
Txhawm rau cais qhov sib xyaw ntawm cov xim uas yog ob lub dyes, daim ntawv chromatography yog siv. Ib feem me me ntawm qhov sib tov yog muab tso rau hauv cov khoom siv absorbent, ib daim ntawv lim, nrog cov kuab tshuaj. Ob lub dyes yuav txav mus rau nyias thiab tus number case yuav sib cais rau hauv nws cov khoom ntshiab
Koj yuav daws qhov sib npaug li cas los ntawm kev cais qhov sib txawv?
Cov txheej txheem yooj yim los cais qhov sib txawv yog "ua ib yam dab tsi rau ob tog" ntawm qhov sib npaug, xws li ntxiv, rho tawm, sib npaug, lossis faib ob sab ntawm qhov sib npaug los ntawm tib tus lej. Los ntawm kev rov ua cov txheej txheem no, peb tuaj yeem tau txais qhov sib txawv ntawm ib sab ntawm qhov sib npaug
